Which term is the effect of all the diamond's internal and external reflections of white light?

• A. Bearded Girdle
• B. Brightness
• C. Belly
• D. Blocking

Answer: (B)

Brightness is the term that describes the overall return of white light to the observer from a diamond. It captures the combined effect of all light reflections inside the stone (internal reflections) and the light bouncing off its surfaces (external reflections). A well-cut diamond plays with its facets to maximize those reflections, guiding more light back to your eye and increasing perceived brightness. Other terms describe different aspects or physical features, not the total white-light return, so they don’t capture this full light-retrieval effect.
